These are largely used for bedding as well as for greenhouse decoration. They have large leaves and erect trusses of very brilliant flowers, red, crimson, orange and yellow in colour.

They may be grown in exactly the same way as the Dahlia, or, if preferred, they may be grown in pots in the unhealed greenhouse, through the summer months. Store the roots like Dahlia tubers in dry soil or sand in a frost-proof place.

Propagate by division of the root stocks or by seed. The seeds are rather hard-coated, and many growers advise soaking for a few days before sowing.
